Fuel-it w/jb4 issues

[MrNobody]

Ok I finally got around to installing my fuel-it kit. Issue is I can't connect via Bluetooth or even see econtent on jb4. White wire is in pin 4 bit 0 is enabled. On bms website it shows a gauge called e-content. I don't see that all I have is e85. When I select that I get nothing. I have double checked power wire/ground wire and white wire. Am I missing something?

Have you checked that the white wire pin is pulled all the way into the correct pin position (#4) of the 25 pin harness.

Check the wiring harness on the ethanol content sensor. Make sure it's fully clicked in.

Here's a screenshot of my JB4:

Check this out. It's not the fuel it system but my setup works and I can see the E content on the JB4 gauge.

Yes, I took a pair of pliers to check if it was seated. Also if only the white wire was the issue, I would think I would be able to connect via the fuel it app no?
Just not sure where I'm having an issue. Tonight I will pull the whole thing out again (for the 4th time) and check all the connections.

Ok odd situation. I didn't do anything and noticed my ethanol gauge is running at 1 now... is that normal for 91 octane?

Yes as normal pump gas is typically E10. (assuming 1 = 10%)

The e85 shows 0-100. So I don't think that's correct.

it should show the E content, although mine is always 4-5 less than the fuel it app, so I just look at the fuel it app.

I cant get my fuelit app to even connect. I can see it in my available devices though.

Strange... after about an hour of having my fuel it app open it required a firmware update. Now im able to connect. But even that is still only showing e01. Wonder if the petrol I have in is truly ethanol free.

Ah ok, here in the U.S it’s E10 by default. Not sure what the default is for where you live

Typical is 5 to 10% ethanol even with non-ethanol 91 or 93. Im in the lower 48.

I see, it should say e10 if it’s working correctly. I thought you were oversea cuz you said “petrol” haha

Lol, sorry im a petrol head, so I have a tendency to use the word petrol. I didn't even realize I did it. Sorry for the confusion.
